Chrysler is recalling more than 600,000 Dodge Durango and Jeep Grand Cherokee sport-utility vehicles for brake boosters that may prematurely corrode. If this occurs, the brake booster can perforate and may ingest water when driving during wet weather.
Should this occur, braking performance can be compromised if the water inside the booster freezes. The driver may have to apply additional application force to stop the vehicle during sub-freezing driving conditions. Unexpected brake force application requirement could slow the driver's brake application reaction time and cause a crash without warning.
All involved vehicles in this action must have the brake booster inspected for corrosion. Brake boosters found with excessive corrosion will be replaced and the boosters will be fitted with a shield to protect the booster crimp joints from water exposure.
Because this is such a large set of vehicles, it is advised that customers call their local dealerships with their vehicle VIN (Vehicle Identification Number) to determine if their vehicle is involved in this recall.
Call Chrysler direct at 1-800-247-9763 or the NHTSA at 1-888-327-4236 and reference Recall #P14/NHTSA 14V -154.
